the following is a slxeitiei'itio'n.

This inventioi,relates to the art or process 'of forming from suitable stock', and placing in l'mxes'. closures ot' proper shape,

ere the closure is made, stopping it, shaping it, andfholding it in alinementwith the cap-forming and inserting plungers, and moving it'oxr to be replaced by another, have been so heavy that. the speed limit of the machine 'was soon reached; whereas, the `presentmachine, having only rotary motion,

will .work-at speeds dependentonly upon the rapidity with which the en'xptyY box-tubes are gotton np to the machine, that is,"a speed fast enough to handle the eon'ibined output 'ot' several of the tubewinders non' obtainable in open market, and mach faster than the tubes can be put into the machine 'byha'nfh .In the drawings, Figitre ll is a diagraml"ig. 2 a

Located above, andsmnewhat to the right of the box-carryzingwvheel, is a second lwheel Il havingcutting-punches lv mounted thereon 4-and 'so spaced as to step into the cutting dies in zthe rim I).

This "wheel M also'` .has pins K projecting radially from the rim. These giiide pins 'on both the wheels H and L step'in'to the holes G in the wheel .B and keepthe three wheels in proper operative relation so that the drawing"plungers Will-enter the drawing dies, andthe rotting-punches will pass into the cuttingdies without striking their edges. These rolling cutters cutl with` surprisingly 'little resistance owing to theishearing aetionj re@ from their shape and the 'tact that vthe, b uiting-punch does not meet thc Adie squarely but 1n successive portions of the meeting surfaces.

1t has -been found that drawingplangers be more or less rounded, especially at .the edgesfwhere the face and the periphery meet, that the entering caps have little or no tenden'ey to Abreak downl the Wall of thebox at the open en'd edges.`

i lVhen the boxes N arel placed in .the chute i' O they roll down to the wheel, and into'the pockets .as the' latter ApassA the endv ofthe l.

chute. Each'looic is,l therefore, carried up under the blanking wheel and a diskv is pn'i'iched'from the strip l of 'aper or other suitable material, drawn ot airoll (not shown), and left lyingin the die,rc`sting on the drawing-die immediately abovethe box. [Advancingy these disks come under the drmving'ivheel and the dravvinr'sf'hplunfV gers which are ofsuch length that they n otl only flange. the diskintoacap but force it down through the die' and into the open end;

thence carried over the idler S to be diS- I disk out from this strip remains in the die 40. as 'none ofthe parts of the machine has i11- .of the box. The 4continued rotation of the box-wheel causes the plungers to withdraw and brings the capped box aroundto the finger Q which forces it out of the pocket,

5 theV finger passing -in behind' the box in the groove R. The aper waste hasa tendency to Stick on the blJanking-cutters, but, as willl be obvious from the size 4and location of the ring J, it is pushed off by the ring and is osed of in any suitable manner.

At extreme speeds the boxes rollin down a simple inclined chute sometimes fai 'to get into the pockets C, and to obviate this the lower end of the chute has a more abrupt incline than the main part of the chute n'which Vtendsto force the box into position in .the pockets. This also has had a somewhat unexpected result,v namely, that it tends, by reason of the agitation of the yboxes immediately above, to straighten any boxes which may not lie straight in the chute.

It is thought that the operation ofthe machine will now be readily understood: namely, As the-box-carrying wheel rotates itpicli.J up boxesv from the chute, carrying them upA vunder `the blanking-wheel which cuts 'a blank or disk from the strip. The

immediately/'above each box and as the wheel advances each box is brought in turn under'the drawing-plunger wheel and the drawingfplunger pushes the disk down through the drawing die and into the open end of the box. The further rotation of the y wheel withdraws the plungerl leaving the closure in the box, after which the capped lboxesare thrown out of themachine, All j the boxes follow these .successive steps, an'd terniittent motion,`th e several o rations are erforxned -smoothl Aand q'uietl);57 and at a speed limited only y the rate 'at which .the boxes are su pulley, gearing or, other anita" l dies to out` disks from ifo i plied to the machine.

Anysuita e power may be employed to rotate the wheels, for instance, by a bi n "rating wheel if,

device located on the shat f for example.
